Theoretically speaking no, because USB3 can run with faster speeds; however
the audio industry will probably not adopt or switch to USB3, as a matter of
fact, I've seen very little equipment that has come out in USB3 versions,
none of which are pro audio.
Another downfall of USB is that everything uses it, from keyboard to mouse
to peripherals, and because the hub has to share so many ports, the
bandwidth gets limitted on everything, including interfaces; firewire on the
other hand usually has 2 ports or 3 at most, and you're told to not use
anything that requires high bandwidth on the additional port when using your
interface/device. A USB keyboard isn't really a high-bandwidth device, but
when many small devices like that add up, dpc and interrupts and such add
up, and that's probably why it is that way for USB.
HTH, D!J!X!
